HF input signal is applied to the centre tapping, and the diodes, other terminals are connected through a resistor to a charging capacitor from which the output signal is collected. An input signal (UE) is applied to the coil centre tapping through a coupling capacitor (CK), and a capacitor (C4) with high impedance for h.f. connects a coil terminal with the diode (D2) to the reference potential. When the coupling capacitor (CK) has its capacitance corresponding to optimum linearity of demodulator characteristic, the capacitance is such that phase difference between input signal voltage and voltages at coil halves is 90 deg. at the circuit centre frequency. Signal voltage at demodulator output disappears.
